Absolutely not. Both the spirit of the Law and the most recent case-law have determined that at the time of purchasing a timeshare, the legal maximum allowed is 50 years.

It depends on the year in which you purchased the week, but in general terms, no. Usually the resorts, while maintaining the floating nature of the week, by their operating system usually grant a pre-fixed accommodation.
Usually the resorts, while maintaining the de facto floating nature of the week, by operating system usually grant a pre-fixed accommodation, but it is not usually exclusive. 

Yes, it is advisable to continue paying the community fees. The behaviour of the claimant is taken into account at all times, especially in order to defend a good strategy in the legal proceedings and also because the contract remains in force until a court ruling declares otherwise.

You can do so without any problem. It is not necessary to go to the out-of-court injunction. However, depending on the type and content of the contract and the complex, it could be interesting to resort to a preliminary injunction, depending on the case.

No, it is not. The law requires that the consumer needs a cooling-off period to make the best possible decision. For this, the law provides for serious consequences for the resort or the resort.

Absolutely not. It must be analysed one by one, case by case. What is more, in some contracts, due to the date on which the contract was signed, however much non-compliance it may contain, as they were signed prior to the entry into force of the Law that protects such contracts, it is improbable that the claim will be successful.

This type of conduct is often disguised as a bonus week or a gift from the resort for which you pay a token amount, dressed up as a separate contract that has nothing to do with the main contract.
Usually this type of conduct on the part of the resort is to charge a price before the cooling off period established by law. This conduct is not correct and should be sanctioned. The place and date of conclusion of this contract, in relation to the main contract, should be analysed.

Yes, you can be sued. Even the notification for unpaid maintenance fees in the Complex where you have your week is usually valid. Depending on how the process of recovery of the debt in case of non-payment is foreseen in the Statutes of the Club or the Community Rules, they can occupy it or deny you access, depending on what the statutes of the Club state.
There are other ways, such as, for example, that the Complex can go to a foreign debt recovery firm to recover the debt directly in your country.

Products where destination flexibility is left to the discretion of the resorts are very common. The flexibility in destinations and the periodic payment of instalments must in any case respect that your chosen holiday destination is not frustrated, basically, because they must guarantee you exclusivity in the product, if it has been contracted in that sense.

Absolutely not. It must be taken into account that the waiver of a right must necessarily be accepted by the other party. The silence of the resort in the face of such a decision does not mean that it accepts a waiver, as it must be taken into account that the week is usually part of a Club or a Community, so that the waiver would imply a possible effect on the other holders of weeks (with regard to the maintenance fees), so that a waiver is not admissible when it is in condominium with other holders of weeks.
